Keeping this in view, why won't my sprinkler heads rotate?

When the water pressure is too low, an inadequate amount of water flows through the sprinkler head and it will not turn. Using a larger backflow preventer in the water line might increase the water pressure enough to cause the sprinkler head to rotate.

Furthermore, how do you rotate a sprinkler head? Turn off the water, lift the gear-driven pop-up sprinkler out of the ground and rotate the head clockwise as far as it will go. Turn the adjustment screw on the sprinkler head counterclockwise as far as it will go with a flat-head screwdriver. This zeros the spray pattern.

Simply so, why does my sprinkler get stuck?

Water pressure that is either too low or too high can cause sprinkler head jamming. When water pressure dips below acceptable limits, the sprinkler head may get stuck at one side of its arc or it may not move at all. If water pressure is too high, it may also cause the sprinkler to stop or jam.

Why do oscillating sprinklers stop working?

When the water pressure is too low, there isn't enough pressure to move the distribution/cylinder bar back and forth. Depending on how low the water pressure is, the sprinkler can move extremely slow to one side, but may not have enough pressure for it to pivot back. This results in no oscillation.

How do I adjust my sprinkler pressure?

Adjust the master valve of your sprinkler system by turning the flow control clockwise until the stream of water from the nozzle begins to drop. This lowers the water pressure. Turn the flow master valve flow control slowly until the spray pattern reaches its full radius.
